96 /* analyse_stack uses the intermediate code created by parse.c to
97 * build a model of the JVM operand stack for the current method.
99 * The following checks are performed:
100 * - check for operand stack underflow (before each instruction)
101 * - check for operand stack overflow (after[1] each instruction)
102 * - check for matching stack depth at merging points
103 * - check for matching basic types[2] at merging points
104 * - check basic types for instruction input (except for BUILTIN*
105 * opcodes, INVOKE* opcodes and MULTIANEWARRAY)
107 * [1]) Checking this after the instruction should be ok. parse.c
108 * counts the number of required stack slots in such a way that it is
109 * only vital that we don't exceed `maxstack` at basic block
112 * [2]) 'basic types' means the distinction between INT, LONG, FLOAT,
113 * DOUBLE and ADDRESS types. Subtypes of INT and different ADDRESS
114 * types are not discerned.
